I am unable to install with Xcode 4.5 and CLI Tools installed

I have used the Redis::hiredis module on many Linux systems, but now that I developing on a OS X Mountain Lion I am receiving the following error when I attempt to make the module. Potentially an issue with compiling with clang over gcc?

Looks good

Looks like by manually changing the Makefile CC = clang to CC = gcc the compile work properly and all test passed.
